12 Models questions from the Concurrency bank, written for Indian campus drives and tech interviews. Every question has a verified answer and an AI-tutor explanation on placd.
Free to start: the 2-minute IT readiness check — six questions and a result.
A.a concurrency approach where tasks communicate by exchanging discrete data through channels or mailboxes instead of touching common state
B.a paradigm in which isolated entities own private state and interact solely by sending asynchronous messages handled one at a time
C.a concurrency approach where tasks communicate by reading and writing common mutable state, requiring explicit synchronization
D.a formal model where independent processes coordinate by synchronous handoffs over named channels, the basis of Go's goroutines and channels
